The invention discloses a method and device for determining the yaw moment of a vehicle and a storage medium, and the method comprises the steps: obtaining the current yaw velocity of the vehicle and the current driving information of the vehicle when it is detected that the vehicle is about to enter a turning state; according to the current yaw velocity of the vehicle and the current driving information of the vehicle, determining an expected yaw velocity of the vehicle and a dynamic disturbance prediction result of the vehicle; based on the current yaw velocity of the vehicle and the expected yaw velocity of the vehicle, constructing an integral synovial surface; determining an expected yaw moment corresponding to the vehicle based on the integral synovial surface and the current driving information of the vehicle; and determining a target yawing moment corresponding to the vehicle based on the dynamic disturbance prediction result and the expected yawing moment. When the vehicle turns at a high speed, the driving torque can be reasonably distributed, the driving strategy of the vehicle is effectively controlled, and the stability of the vehicle in the turning process is ensured.

    本申请公开了一种车辆的横摆力矩确定方法、装置及存储介质,所述方法包括:在检测到车辆即将进入转弯状态时,获取车辆的当前横摆角速度和车辆的当前行驶信息;根据车辆的当前横摆角速度以及车辆的当前行驶信息,确定车辆的期望横摆角速度以及车辆的动态扰动预测结果;基于车辆的当前横摆角速度和车辆的期望横摆角速度,构建积分滑膜面;基于积分滑膜面和车辆的当前行驶信息,确定车辆对应的期望横摆力矩;基于动态扰动预测结果以及期望横摆力矩,确定车辆对应的目标横摆力矩。本申请能在车辆高速转弯时,合理分配驱动扭矩,有效控制车辆的行驶策略,确保车辆在转弯过程中的稳定性。
